Other major functions are described follow:
1. When supply voltage is applied, the output relay pulls in after an initialization period of 3 seconds (approximately),
provided all thermistors lie below their rated response temperature.
2. 1 to 9 PTC thermistors with varied rated response temperatures can be connected in series to input terminals.
3. If any thermistor resistance increases above trip level the relay drops out. This failure results in a lockout. (5 minutes
delay for the 1st PTC failure, 60 minutes delay for the 2nd failure, eternal lockout for the 3rd failure until manual
reset)
4. Lockout and time delay can be cancelled by mains reset of approx. 5 seconds.
5. LED with red/green light provides operational information.
6. The relay is fed out as a N/O dry contact, which is closed under good conditions.
7. Sensor and supply circuits are galvanic isolated.
Note: Motor protector phase monitor (phase loss and phase sequence) function is not suitable for variable frequency
drive application.

e. Oil heater
One UL approved 150W oil heater has been installed in every compressor as a standard accessory. Before restart of
compressor after shutdown for a long time, please turn on oil heater at least 8 hours to make the temperature inside
compressor higher than system temperature and ambient temperature. This action prevents condensed refrigerant
inside oil sump of compressors which may result in liquid compression in following operations and poor lubrication due
to low viscosity of lubrication oil. Hanbell also offers 300W oil heater to keep adequate lubricant oil temperature for
large external oil separator and applications in areas where the ambient temperature is low.
